What part of "When the voltages in the capacitors are equal you will end up with less than 0.5 Vinitial in both." is not "offering a prediction"?

--- End quote ---

Show me the math you use to get to that conclusion.
The question I asked involves a DC-DC converter with constant current control between the two capacitors and total efficiency of 80%.
Say you start at 3V for the charged capacitor and you stop the discharge when the charged capacitor voltage drops to 2.121V so half the initial energy.
What will be the voltage on the other capacitor the one that started empty at 0V.

What you are saying is "If I had a Unicorn, then I could open a Unicorn Zoo - prove me wrong!".

No, you prove me wrong. Show me your unicorn!

--- End quote ---
Very funny. The only thing I did in this thread was to indicate all the experimental data that support the energy flowing in space.

--- End quote ---
Really, where then?
Please explain what experiment was done, what S=JV predicted, what Poynting predicted and what was found.
There's none.

--- Quote ---what was predicted by the S=JV folks, and what was found. (And why Poynting-Heaviside-etc. do not talk about it.)

--- End quote ---
What they accomplished no one knows. What they didn't, we know. They didn't manage to come up with an alternative that doesn't break causality, locality, gauge invariance or a combination of these.

That's why, despite objections regarding its counterintuitive nature, Poynting is the most probable explanation for the flow of energy.

--- End quote ---
You gave no example of an alternative breaking any of this ;D . Coincidence?

--- Quote ---I also wonder how exactly all physicists proposing alternatives to the Poynting theorem never saw Derek's antennae coming in the whole 20th century. They must feel very silly now (no).

--- End quote ---
They didn't. But their peers did and criticized their proposals. That's why Poynting still stands.

--- End quote ---
Sure so in the 20th century and 21st physicists never heard of antennae.  ::)

You will think that it is a unicorn because you do not understand the subject. It is in fact just a simple horse :)

But here is the proof

And it doesn't bother you at all that there is no circuit you can put in region A in the diagram below that can extract energy from the wires that surround it? Even a DC/DC convertor? Even if you can connect it to a GND? But extracting energy from regions B or C is a piece of cake?

--- End quote ---
And it doesn't bother you at all that energy is supposedly flowing through the region A yet there is no circuit you can put in region A in the diagram that can extract energy from it?
(Hopefully the answer is no)

--- Quote from: hamster_nz on May 12, 2022, 08:09:21 am ---And it doesn't bother you that for your version of electrostatics  (sum of force between charges), every charge needs to be in consistent communication with every other charge in the universe, to work out how far away they are, and at what direction?

--- End quote ---
Are you bothered???
Do you think that if every electron could communicate with far away electrons, humans could make machines hacking this property to communicate messages?

--- Quote from: hamster_nz on May 12, 2022, 08:09:21 am ---And it doesn't bother you that a transmission line is a series of inductors and capacitors, however on inspection those capacitors and inductors can neither be identified or isolated?

--- End quote ---
A wire is an inductor. With 2 you have an inductor and half a capacitor. And it works even for infinitesimal wires.  8)
